9.1 Safety instructions for maintenance
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions (Page 13)
● Comply with the applicable national and sector-specific regulations at the place of 
installation
● When using the machine within the European Union, comply with the specifications laid 
down in EN 50110‑1 regarding safe operation of electrical equipment.
Through careful and regular maintenance, inspections, and overhauls you can detect faults at 
an early stage and resolve them. This means that you can avoid consequential damage.
Operating conditions and characteristics can vary widely. For this reason, only general 
maintenance intervals can be specified here. Maintenance intervals should therefore be 
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).  
Note
Please contact the service center (Page 99), if you require support with service, maintenance 
or repair.
9.2 Inspection and maintenance
9.2.1 Safety instructions
WARNING
Rotating and live parts
Electric machines contain live and rotating parts. Fatal or serious injuries and substantial 
material damage can occur if maintenance work is performed on the machine when it is not 
stopped or not de-energized.
● Perform maintenance work on the machine only when it is stopped. The only operation 
permissible while the machine is rotating is regreasing the rolling bearings.
● When performing maintenance work, comply with the five safety rules (Page 13).
